AI Technical Summary
The existing controller filter device is not visible, leading to blind replacement during maintenance, short service life, and waste.
A visual indicator filter cartridge device was designed. Through the combination of a transparent shell, an elastic membrane and an indicator needle, impurities are settled by utilizing the principles of gas rotation and centrifugation. The indicator needle displays the blockage status and prompts for filter cartridge replacement.
It enables visual monitoring of filter clogging, avoiding unnecessary replacements, reducing waste, and extending the service life of the filter.
